looks cool...its a bit dark though and honestly to show it I'd get rid of the background. Use it for lighting but exclude it from the render visablity, it just clutters up what you're looking at.
well atleast youve done deecent verion of the VERY common theme. NOt the best ive sen but atleast its ilit pretty well... could it be that the image is without a aprofile here, itd be nice as your gamma ia so wasty different form mine.
